[0094] An electronic device according to various example
embodiments can include a communication interface for receiving
information from an external device, and a processor. The processor
can allow to output a haptic effect for at least one Braille key
among a plurality of Braille keys, based on the information
received through the communication interface.
[0095] In one example embodiment, the plurality of Braille keys can
be implemented using Electro-Mechanical Polymers (EMPs).
[0096] In one example embodiment, the haptic effect for the at
least one Braille key can include a vibration or tactile response
of the at least one Braille key.
[0097] In one exemplary embodiment, the processor can allow to
determine data to output the haptic effect based at least on the
received information and, if receiving a touch input for a Braille
key mapped to the determined data, output a haptic effect for the
Braille key mapped to the determined data.
[0098] In one example embodiment, while receiving the touch input
for the Braille key mapped to the determined data, the processor
can output the haptic effect, and determine data corresponding to
the next order of the determined data, as the data to output the
haptic effect.
[0099] In one example embodiment, the processor can determine data
to output the haptic effect based at least on the received
information, and output a haptic effect for a Braille key mapped to
the determined data.
[0100] In one example embodiment, if receiving a touch input for
the mapped Braille key, the processor can determine data
corresponding to the next order of the determined data, as the data
to output the haptic effect.
[0101] In one example embodiment, if receiving a touch input from a
user, the processor can allow to sequentially output each of data
included in the received information using the haptic effect.
[0102] In one example embodiment, if receiving the information
through the communication interface, the processor can allow to
output a notification notifying the information reception.
[0103] FIG. 4 is a conceptual diagram illustrating an example
method for providing information according to one example
embodiment.
[0104] FIG. 4 illustrates an example of a Braille chart 410 (or
Braille table) including a plurality of Braille and the electronic
device 101 capable of inputting or outputting the plurality of
Braille.
[0105] In one example embodiment, Braille exemplifies English
language (or alphabet) Braille, but is not limited to this. For
example, Braille can include Braille corresponding to a Korean
language (or Korean) (e.g., an initial consonant, a vowel, a final
consonant, an abbreviated syllable, and an abbreviated word), a
numeral, and a punctuation mark, as well as an English
language.
[0106] In one example embodiment, if receiving information from an
external device, the electronic device 101 can output the received
information in a haptic form using at least one Braille key. For
example, in case where the electronic device 101 includes a
plurality of Braille keys, the electronic device 101 can extract
data included in the received information, and output a haptic
effect for a Braille key mapped to each of the extracted data. In
another example embodiment, the electronic device 101 can output,
in a haptic form, Braille corresponding to the information received
from the external device on the display 160. For example, the
electronic device 101 can output the haptic effect to at least a
part of the display 160 to represent Braille corresponding to the
information received from the external device. In one example
embodiment, the haptic effect can include a vibration or tactile
response. However, it is not limited to this. In one example
embodiment, the display 160 can include a tactile display.
[0107] In one example embodiment, the electronic device 101 can
output a haptic effect to a part of the electronic device 101 as
well as the whole electronic device 101. For example, the
electronic device 101 can output the haptic effect such that the
whole electronic device 101 is vibrated. In another example, the
electronic device 101 can output the haptic effect such that only a
part of a construction of the electronic device 101 is vibrated.
For example, in case where the electronic device 101 includes a
keyboard, the electronic device 101 can allow to vibrate only some
Braille keys among a plurality of Braille keys or induce tactile
responses of the some Braille keys.
[0108] In one example embodiment, in case where a plurality of
touches (or contacts) are inputted to the electronic device 101,
the electronic device 101 can recognize or disregard the touch
input in accordance with a position of the touch input within the
electronic device 101. For example, the electronic device 101 can
include a plurality of Braille keys and output a haptic effect for
at least one Braille key among the plurality of Braille keys. If a
user's touch is inputted, for example, to the whole plurality of
Braille keys, the electronic device 101 can recognize only an input
for at least one Braille key that is outputting the haptic effect,
and disregard inputs for the remnant Braille keys.
[0109] In one example embodiment, the electronic device 101 can
include the portable terminal 430 including a display, the notebook
computer 440, etc. as well as the keyboard 420. However, the
electronic device 101 including the display is not limited to
this.
[0110] In one example embodiment, the electronic device 101 can
output a haptic effect for a partial region of the display. For
example, the electronic device 101 can display a plurality of
Braille keys on the display. The electronic device 101 can output a
haptic effect for at least one Braille key displayed in a partial
region of the display among the plurality of Braille keys.
[0111] FIGS. 5A and 5B are diagrams illustrating an example
principle of outputting a plurality of Braille keys according to
one example embodiment.
[0112] In one example embodiment, the electronic device 101 can
include a plurality of Braille keys capable of outputting a haptic
effect.
[0113] In one example embodiment, the plurality of Braille keys can
be implemented using Electro-Mechanical Polymers (EMPs). For
example, the plurality of keys can be each comprised of EMPs. In
another example, the plurality of Braille keys can be implemented
in a form in which the plurality of Braille keys are each coated
with the EMPs.
[0114] In a further example, the plurality of Braille keys can be
outputted on a tactile display. For example, the plurality of
Braille keys can include an EMP layer in which EMP is arranged
every position corresponding to a position that is set to output
Braille on the display. In one example embodiment, the EMP layer
can be laminated on a window of the display 160. In another example
embodiment, in case where the display 160 is implemented as a
Liquid Crystal Display (LCD), the EMP layer can be implemented to
be located between a backlight unit and a housing of the electronic
device 101 or a construction of another electronic device 101.
However, it is not limited to this. For example, the electronic
device 101 can include various types of tactile displays in order
to output Braille (or Braille keys).
[0115] In one example embodiment, the EMPs can include relaxor
ferroelectric electrostictive polymers.
[0116] In one example embodiment, the EMPs can have high strain (or
tensile) and modulus (i.e., the elastic modulus representing a
ratio of stress and strain) compared to other materials. For
example, the EMPs can be excellent in aspects of a thickness at
actuator implementation, an elastic energy density, a driving
voltage at haptic effect output, electric field formation, etc. as
well as a strain and the elastic modulus (Mpa), compared to
piezoelectric ceramic materials such as lead zirconate titanate
(PZT) and dielectric Electro-Active Polymers (dEAPs).
[0117] In one example embodiment, the electronic device 101 can
output a haptic effect for at least one Braille key among a
plurality of Braille keys.
[0118] For example, if electricity (or a signal) is applied to EMPs
included in each at least one Braille key among a plurality of
Braille keys in accordance with a control signal, the EMPs can be
deformed physically. For example, in a state in which electricity
is not applied to the EMPs, electric charges included within
molecules of the EMPs can be distributed in disorder. For example,
as illustrated in FIG. 5A, the EMPs can include molecules in which
electric dipoles of respectively different directions are
formed.
[0119] In another example, if electricity is applied to the EMPs
included in each of the plurality of Braille keys, an electric
field can be generated within the EMPs. By the generated electric
field, the electric dipoles formed in the respective molecules
constructing the EMPs can be formed in the same direction (or an
electric dipole moment having the same direction can be induced).
According as the electric dipoles of the respective molecules
included within the EMPs are formed in the same direction, a shape
(or form) of the respective molecules included within the EMPs can
be deformed (or changed) physically. For example, as illustrated in
FIG. 5B, the respective molecules of the EMPs of hexagonal forms of
FIG. 5A can be deformed in shape to have a form of extending at one
axis. In one example embodiment, in case where physical deformation
is made, for example, the respective molecules of the EMPs are
physically deformed in shape, the electronic device 101 can output
a haptic effect for a Braille key including the EMPs.
[0120] In one example embodiment, the electronic device 101 can
detect a touch (or contact) on at least lone Braille key among a
plurality of Braille keys.
[0121] For example, in case where a plurality of Braille keys each
includes EMPs, if a user touches (contacts with) at least one
Braille key among a plurality of keys, the electronic device 101
can detect the touched at least one Braille key. For example, if a
physical force is applied to EMPs included in each of at least one
Braille key among the plurality of Braille keys, the EMPs can
generate electricity. By identifying the Braille key including the
EMPs in which electricity is generated, the electronic device 101
can detect the touch on (or contact with) the at least one Braille
key among the plurality of Braille keys. In one example embodiment,
the touch input for the plurality of Braille keys can include a
touch input using one finger (e.g., a drag input using one finger),
a multi touch input by at least two or more fingers, an input
rubbing the plurality of Braille keys (or a flicking input), a
long-touch input of a designated time or more for the plurality of
Braille keys, etc. However, it is not limited to this.
[0122] In one example embodiment, each Braille key can include six
dots (a dot 1 to a dot 6) for representing Braille. In one example
embodiment, the six dots can be implemented in a form in which the
six dots are engraved within the Braille key. In another example
embodiment, the six dots can be implemented in a form in which a
sheet on which the six dots are printed is attached to the Braille
key. However, it is not limited to this.
[0123] FIG. 6 is a flowchart illustrating an example method for
providing information according to one example embodiment.
[0124] Referring to FIG. 6, in operation 601, the processor 120 can
receive information from an external device. In one example
embodiment, the information received from the external device can
include information transmitted through a text message (e.g., a
Short Message Service (SMS), a Multimedia Messaging Service (MMS),
etc.), a mail, a messenger service, etc. However, it is not limited
to this.
[0125] In one example embodiment, the received information can
include a text including at least one of an English language, a
Korean language, a numeral, and a special character. However, it is
not limited to this.
[0126] In one example embodiment, the received information can
include user information of the external device. For example, the
received information can include a user name of the external
device, a telephone number thereof, etc.
[0127] In one example embodiment, in operation 603, the processor
120 can allow to output a notification based at least on the
received information. For example, the processor 120 can control
the speaker 282 to output the notification in a sound form. In
another example, the processor 120 can control the motor 298 to
output the notification in a form of outputting a vibration of the
whole electronic device 101. However, it is not limited to this,
and the processor 120 can allow to output the notification in a
light form.
[0128] In one example embodiment, the processor 120 can output a
notification by outputting a haptic effect for at least one Braille
key among a plurality of Braille keys. For example, in case where
the electronic device 101 includes a keypad and a plurality of
Braille keys within the keypad are implemented using EMPs, the
processor 120 can allow to output a haptic effect such as a
vibration, a tactile response, etc. by applying a signal (or
electricity) to the EMPs included in each at least one Braille key
among the plurality of Braille keys. In one example embodiment, the
Braille key can denote a key including six dots (a dot 1 to a dot
6) such that Braille reading is available.
[0129] However, in accordance with an example embodiment, operation
603 can be omitted. For example, a separate notification output
operation is omissible in case where the processor 120 sets to
straight output a haptic effect for a Braille key corresponding to
data included in information received from an external device,
after receiving the information from the external device. However,
it is not limited to this.
[0130] In one example embodiment, in operation 605, the processor
120 can allow to output a haptic effect for at least one Braille
key corresponding to text data of the received information that
includes sender information.
[0131] In one example embodiment, the processor 120 can extract (or
classify) a text included in the received information by the unit
of data capable of being outputted through a Braille key. In one
example embodiment, the unit of data capable of being outputted
through the Braille key can be a unit capable of recognizing the
order of any one piece of data among a plurality of pieces of data
included within a text and the data (or data content) by an
operation of a user's one-time touch on the whole plurality of
Braille keys constructing a keypad.
[0132] In one example embodiment, in case where the received
information includes an English language text, the processor 120
can extract each data of an alphabet unit in order from the English
language text. For example, in case where the received information
includes an English language text `kang`, the processor 120 can
extract (classify) each data of an alphabet unit in order of `k`,
`a`, `n`, and `g` from the `kang`. In another example embodiment,
in case where the received information includes a Korean language
(or Korean) text, the processor 120 can extract data of a phoneme
or letter unit. For example, in case where the received information
includes a Korean language text ``, the processor 120 can extract
data of a phoneme unit in order of phonemes constructing the text,
such as ``, ``, ``, ``, ``, ``, ``, ``, and ``. In another example,
in case where the received information includes the Korean language
text ``, the processor 120 can extract data of a letter unit in
order of letters such as ``, ``, and ``.
[0133] In one example embodiment, in case where the received
information includes a numeral, the processor 120 can extract data
by the unit of one numeral in order of constructing the numeral.
For example, in case where the received information includes a
numeral `101`, the processor 120 can extract data by the unit of
one numeral in order of `1`, `0`, and `1`.
[0134] However, the data the processor 120 is possible to extract
from the received information is not limited to this. For example,
the processor 120 can extract data on a special character such as a
symbol, etc.
[0135] In one example embodiment, in case where the received
information includes a text that is a combination of at least one
of an English language, a Korean language, a numeral, and a special
character, the processor 120 can extract the text included in the
received information by the unit of data capable of being outputted
through Braille keys. For example, in case where the received
information includes a combined text `kang 1`, the processor 120
can extract data capable of being outputted through Braille keys in
order of `k`, `a`, `n`, `g`, ``, ``, ``, and `1`.
[0136] In one example embodiment, the processor 120 can output a
haptic effect for a Braille key to represent Braille corresponding
to the extracted data. For example, the processor 120 can output
the haptic effect (e.g., tactile response) on the display 160
(e.g., a tactile display) such that dots constructing the Braille
key are embossed in a hemispheric form (or protrusion form) in
order to represent Braille corresponding to the extracted data. A
detailed description of this is made in later with reference to
FIG. 7.
[0137] In one example embodiment, the processor 120 can output a
haptic effect for a Braille key mapped to each data that is
extracted by a unit capable of being outputted.
[0138] In one example embodiment, the processor 120 can allow to
output a haptic effect for a Braille key mapped to data for which
haptic effect output is determined, in response to a user's touch
input for the Braille key mapped to the data for which the haptic
effect output is determined. For example, the processor 120 can
determine data to output the haptic effect, in order of data
constructing a text included in the received information. If the
user's touch input for the Braille key mapped to the determined
data is received, the processor 120 can allow to output the haptic
effect for the Braille key mapped to the determined data. A
detailed description will be made with reference to FIG. 7 for the
operation of outputting the haptic effect for the Braille key
mapped to the data for which the haptic effect output is
determined, in response to the user's touch input for the Braille
key mapped to the data for which the haptic effect output is
determined.
[0139] In one example embodiment, the processor 120 can output a
haptic effect for a Braille key mapped to data for which haptic
effect output is determined and, in response to a user's touch
input, output a haptic effect for a Braille key mapped to data
corresponding to the next order of the data mapped to the Braille
key for which the haptic effect is outputted. Operation of this
will be described in detail with reference to FIG. 11.
[0140] In one example embodiment, in response to a user's touch
input, while receiving the touch input, the processor 120 can
sequentially output a haptic effect for a Braille key mapped to
data constructing a text included in received information.
Operation of this will be described in detail with reference to
FIG. 12 to FIG. 14.
[0141] In one example embodiment, the processor 120 can further
perform an operation of determining Braille corresponding to data
constructing a text included in received information. For example,
in case where a text is comprised of at least one of an English
language, a Korean language, a numeral, and a special character,
the processor 120 can determine Braille corresponding to data on
the at least one of the English language, the Korean language, the
numeral, and the special character. For example, the processor 120
can determine Braille corresponding to the data constructing the
text, using a Braille chart (or Braille table). In one example
embodiment, the processor 120 can allow to output a haptic effect
for a Braille key mapped to the determined Braille.
[0142] In one example embodiment, operation 605 can be executed
under a designated condition.
[0143] For example, the processor 120 can output a haptic effect
for at least one Braille key in accordance with situation
information. For example, the processor 120 can set to output the
haptic effect for the at least one Braille key when the situation
information around the electronic device, for example, noise is
equal to or is greater than a designated level. In another example,
the processor 120 can control a display to display received
information when the noise is equal to or is less than the
designated level. However, the situation information is not limited
to the noise, and can include a variety of situations around the
electronic device.
[0144] In another example, the processor 120 can determine the
output or non-output of a haptic effect for at least one Braille
key in accordance with notification output setting of received
information. For example, in case where the notification output
setting is set as a sound, the processor 120 can determine to
output the received information by the sound. In another example,
in case where the notification output setting is set as a
vibration, light, or mute, the processor 120 can determine to
output the haptic effect for the at least one Braille key. However,
it is not limited to this.
[0145] FIGS. 7A and 7B are diagrams illustrating an example method
of outputting a haptic effect for at least one Braille key among a
plurality of Braille keys according to another example
embodiment.
[0146] FIG. 7A and FIG. 7B illustrate examples of outputting a
haptic effect for a Braille key in order to represent Braille
corresponding to data that is extracted from information received
from an external device. For example, FIG. 7A illustrates an
example of, in case where the extracted data includes `kang`,
outputting a haptic effect (or a tactile response) for at least one
Braille key in order to represent Braille corresponding to the
`kang` on the display 160 (e.g., a tactile display).
[0147] In one example embodiment, if information is received from
an external device, the electronic device 101 can output a virtual
(or soft) Braille key in a partial region of the display 160. For
example, as illustrated in FIG. 7A, the electronic device 101 can
output four Braille keys 710, 720, 730, and 740. In another example
embodiment, if the information is received from the external
device, the electronic device 101 can output a virtual (or soft)
Braille key in the whole region of the display 160 as well.
[0148] In one example embodiment, by outputting a haptic effect for
dots included in each of a plurality of Braille keys, the
electronic device 101 can allow a user to recognize data (or
Braille corresponding to the data) included in received
information. For example, the electronic device 101 can output a
tactile response of dots within a Braille key such that the dots
are embossed in a hemispheric form (or protrusion form). For
example, the electronic device 101 can allow dots 711 and 713
within a Braille key 710 to be embossed in order to represent
Braille corresponding to `k`. The electronic device 101 can allow a
dot 721 within a Braille key 720 to be embossed in order to
represent Braille corresponding to `a`. The electronic device 101
can allow dots 731, 732, 733, and 734 within a Braille key 730 to
be embossed in order to represent Braille corresponding to `n`. The
electronic device 101 can allow dots 741, 742, 743, and 744 within
a Braille key 740 to be embossed in order to represent Braille
corresponding to `g`.
[0149] In one example embodiment, a user can recognize data
included in received information, by touching Braille keys for
which a haptic effect for dots is outputted using the finger.
[0150] FIG. 7A illustrates that Braille corresponding to data
`kang` is outputted from the left to the right, but is not limited
to this. For example, the Braille corresponding to the data can be
outputted from the right to the left, or be outputted from an upper
end of the display to a lower end thereof or from the lower end of
the display to the upper end thereof.
[0151] In one example embodiment, in case where the number of
pieces of data (or Braille corresponding to the data) included in
received information is greater than the number of Braille keys,
the electronic device 101 can first output Braille corresponding to
a part of the data, and then output Braille corresponding to a part
of the remnant data after receiving a user input. For example, in
case where data is `kangjungho`, the electronic device 101 can
first output four Braille corresponding to `kang` through the
Braille keys 710, 720, 730, and 740, and then output Braille
corresponding to data `jung` following the `kang` through the
Braille keys 710, 720, 730, and 740 after receiving a touch input
for the Braille keys 710, 720, 730, and 740 from a user. If a touch
input for the Braille keys 710, 720, 730, and 740 is again received
from the user while the Braille corresponding to the `jung` is
outputted through the Braille keys 710, 720, 730, and 740, the
electronic device 101 can output Braille corresponding to `ho`
through the Braille keys 710, 720, 730, and 740. In one example
embodiment, after receiving a touch input for Braille keys, the
electronic device 101 outputs Braille corresponding to data of the
next order of data that is being currently outputted, whereby the
user can recognize data included in received information by a
continuous touch operation.
[0152] In one example embodiment, FIG. 7B illustrates an example in
which a keyboard (e.g., a virtual keyboard) is comprised of a
plurality of rows each including a plurality of Braille keys. For
example, the keyboard can include three rows 750, 760, and 770, and
each row can include a plurality of Braille keys.
[0153] In one example embodiment, as illustrated in FIG. 7B, in
case where a keyboard is comprised of a plurality of rows, the
electronic device 101 can output Braille corresponding to a lot of
pieces of data at once. For example, in FIG. 7B, the electronic
device 101 can output Braille corresponding to `kang` at the first
row 750, Braille corresponding to `jung` at the second row 760, and
Braille corresponding to `ho` at the third row 760.
[0154] In one example embodiment, in case where a keyboard includes
a plurality of rows, a user can recognize data by touching a region
of each row. For example, the user can recognize Braille outputted
through the first row 750 by touching (or dragging) Braille keys
751, 752, 753, 754 included in the first row 750 using the finger.
The user can recognize Braille outputted through the second row 760
and the third row 770 by touching Braille keys 761, 762, 763, and
764 included in the second row 760 and Braille keys 771 and 772
included in the third row 770.
[0155] FIG. 7B illustrates that a virtual keyboard includes three
rows and each row includes four Braille keys, but is not limited to
this.
[0156] FIG. 8 is a flowchart illustrating an example method of
outputting a haptic effect for at least one Braille key among a
plurality of Braille keys according to one example embodiment.
[0157] Referring to FIG. 8, in one example embodiment, in operation
801, the processor 120 can determine data to output a haptic
effect. For example, the processor 120 can determine the data to
output the haptic effect (hereinafter, referred to as `determined
data`) in order of data constructing a text included in received
information.
[0158] In one example embodiment, if the processor 120 outputs a
haptic effect for a Braille key mapped to data, the processor 120
can determine data corresponding to the next order (or
corresponding to the next arrangement order) of the data mapped to
the Braille key for which the haptic effect is outputted, as data
to output a haptic effect. For example, in case where received
information includes an English language text `kang`, the processor
120 can determine data `n` arranged following data `a` as the data
to output the haptic effect, after outputting a haptic effect for a
Braille key mapped to the data `a`.
[0159] In operation 803, the processor 120 can receive a touch
input for at least one of a plurality of Braille keys from a
user.
[0160] In one example embodiment, the touch input for the plurality
of Braille keys can include a multi touch input by at least two or
more fingers, a rubbing touch input (or a flicking input), etc. For
example, the touch input for the plurality of Braille keys can be a
touch input rubbing the plurality of Braille keys of the electronic
device 101 (e.g., the keypad) from the left to the right by the
user's hand. However, it is not limited to this. For example, the
touch input for the plurality of Braille keys can include all of an
input by a touch on the plurality of Braille keys such as a multi
touch input for the plurality of Braille keys, a palm touch input
using the palm, etc.
[0161] In one example embodiment, in operation 805, the processor
120 can determine if a touch input for at least one Braille key
(hereinafter, referred to as a `determined Braille key`) mapped to
the determined data among a plurality of Braille keys is received
from a user.
[0162] In one example embodiment, if determining in operation 803
that the touch input for the determined Braille key among the
plurality of Braille keys is not received from the user, in
operation 805, the processor 120 can allow to perform a
corresponding function. For example, the processor 120 can allow to
disregard a touch input for another Braille key, not the determined
Braille key. In another example, if receiving an input for another
function key not a Braille key, the processor 120 can allow to
execute a function mapped to the another function key.
[0163] In one example embodiment, in operation 809, the processor
120 can allow to output a haptic effect for the determined Braille
key. For example, the processor 120 can allow to vibrate the
determined Braille key or induce a tactile response of the
determined Braille key, by means of EMPs included in the determined
Braille key. However, it is not limited to this. For example, the
processor 120 can control the speaker 282 to output Braille mapped
to the determined Braille key in a voice form as well.
[0164] In one example embodiment, the processor 120 can allow to
output a haptic effect for the determined Braille key for a
designated time. For example, the processor 120 can allow to output
the haptic effect for the determined Braille key for a preset time
after a user touches the determined Braille key. In another
example, the processor 120 can allow to output the haptic effect
for the determined Braille key only while the user touches the
determined Braille key. In a further example, the processor 120 can
allow to detect a touch on the determined Braille key and output
the haptic effect for the determined Braille key, while receiving a
touch input for the determined Braille key by the user's finger.
However, it is not limited to this.
[0165] In one example embodiment, in operation 811, the processor
120 can determine if the determined data is the last data
constructing a text. For example, the processor 120 can determine
if it has outputted all of a text included in received information,
or has outputted a haptic effect for a Braille key mapped to each
of the whole data constructing the text included in the received
information. For example, in case where the text included in the
received information is `kang` and the determined data is `g`, the
processor 120 can determine the data `g` as the last data
constructing the text.
[0166] In one example embodiment, if determining in operation 811
that the determined data is not the last data constructing the
text, the processor 120 can return to operation 801 and determine
data following data that is currently determined (or data
corresponding to the next order), as data to output a haptic
effect.
[0167] In one example embodiment, if determining in operation 811
that the determined data is the last data constructing the text,
the processor 120 can end an information provision operation.
[0168] In one example embodiment, in operation 805 if it is
determined that there is not a mapping, the device performs the
corresponding function in operation 807.
[0169] FIG. 9 is a diagram illustrating an example method of
outputting a haptic effect for at least one Braille key among a
plurality of Braille keys according to an example embodiment.
[0170] FIG. 9 illustrates a case in which a plurality of Braille
keys are mapped to English language (or alphabet) data, but it is
not limited to this.
[0171] In one example embodiment, an electronic device 900 can
output a notification of received information, and extract (or
classify) a text included in the received information by the unit
of data capable of being outputted through Braille keys. For
example, in case where the received information includes an English
language text `kang`, the electronic device 900 can extract `k`,
`a`, `n`, and `g` by the unit of data capable of being outputted
through Braille keys, for example, by the unit of alphabet, from
the English language text `kang`.
[0172] In one example embodiment, the electronic device 900 can
determine data to output a haptic effect. For example, in case
where received information includes an English language text
`kang`, the electronic device 900 can determine data `k` arranged
at the head of the English language text `kang`, as the data to
output the haptic effect (hereinafter, referred to as `determined
data`), in order of data constructing the English language text
`kang`. In one example embodiment, the electronic device 900 can
determine a Braille key mapped to the determined data, as a Braille
key to output a haptic effect (hereinafter, referred to as a
`determined Braille key`).
[0173] In one example embodiment, the electronic device 900 can
receive a touch input for a plurality of Braille keys of the
electronic device 900 (e.g., keypad) from a user. For example, as
illustrated in FIG. 9, the electronic device 900 can receive a
touch input by the user's hand 950 in an arrow direction 960 (e.g.,
a direction from the left to the right). The touch input from the
user is not limited to the example of FIG. 9. For example, the
touch input for the plurality of Braille keys can be a multi touch
input by at least two or more fingers. In another example, the
touch input for the plurality of Braille keys can include a touch
input having a direction such as a direction from the right to the
left, a direction from up to down, a direction from down to up,
etc., different from the arrow direction.
[0174] In one example embodiment, the electronic device 900 can
determine if a touch input for the determined Braille key is
received from a user. For example, in case where received
information includes an English language text `kang` and determined
data is `k`, the electronic device 900 can determine if an input by
the user's hand for a Braille key 910 mapped to the data `k` is
received. If the electronic device 900 determines that the touch
input by the user's hand for the Braille key 910 is received, the
electronic device 900 can output a haptic effect for the Braille
key 910. For example, the electronic device 900 can allow to output
a vibration or tactile response of the Braille key 910. In one
example embodiment, the electronic device 900 can output a haptic
effect for the Braille key 910 for a designated time. For example,
the electronic device 900 can output the haptic effect for the
Braille key 910 for a preset time after the user touches the
Braille key 910. In another example, the electronic device 900 can
output the haptic effect for the Braille key 910 only while the
user touches the Braille key 910. In a further example, the
electronic device 900 can allow to detect a touch on the Braille
key 910 and output the haptic effect for the Braille key 910, while
receiving a touch input by the user's finger. However, it is not
limited to this.
[0175] In one example embodiment, if the electronic device 900
outputs a haptic effect for the Braille key 910, in case where
received information includes an English language text `kang` and
determined data is `k`, the electronic device 900 can determine
data `a` following the data `k` (corresponding to the next order)
as data to output a haptic effect. In one example embodiment, the
electronic device 900 can determine a Braille key 920 mapped to the
data `a`, as a Braille key to output a haptic effect. In one
example embodiment, if the electronic device 900 determines that a
touch input by the user's hand for the Braille key 920 is received
from a user, the electronic device 900 can output a haptic effect
for the Braille key 920. In one example embodiment, the electronic
device 900 can determine data `n` following data `a` (or
corresponding to the next order), as data to output a haptic
effect. In one example embodiment, the electronic device 900 can
determine a Braille key 930 mapped to the data `n`, as a Braille
key to output the haptic effect. In one example embodiment, if the
electronic device 900 determines that a touch input by the user's
hand for the Braille key 930 is received from the user, the
electronic device 900 can output a haptic effect for the Braille
key 930. In one example embodiment, the electronic device 900 can
determine data `g` following the data `n` (or corresponding to the
next order), as data to output a haptic effect. In one example
embodiment, the electronic device 900 can determine a Braille key
940 mapped to the data `g`, as a Braille key to output a haptic
effect. In one example embodiment, if the electronic device 900
determines that a touch input by the user's hand for the Braille
key 940 is received from the user, the electronic device 900 can
output a haptic effect for the Braille key 940.
[0176] In one example embodiment, in case where received
information includes an English language text `kang` and the
electronic device 900 completes the outputting of a haptic effect
for each of Braille keys mapped to `j`, `a`, `n`, and `g`, the
electronic device 900 can end an information provision operation or
a haptic effect output operation.
[0177] FIG. 10 is a diagram illustrating an example method of
outputting a haptic effect for at least one Braille key among a
plurality of Braille keys according to another example
embodiment.
[0178] FIG. 10 illustrates a Korean-language Braille chart for
describing a method of outputting a haptic effect for a Braille key
mapped to data constructing a Korean language (or Korean) text in
case where received information includes the text.
[0179] In one example embodiment, in case where received
information includes a Korean language text, the electronic device
101 can output data of a phoneme unit, a letter unit, and a word
unit.
[0180] For example, in case where received information is ``, the
electronic device 101 can output a haptic effect for a Braille key
mapped to each of ``, ``, and `` by the unit of phoneme such as ``,
``, and ``. For example, while receiving a first touch input from a
user, the electronic device 101 can output the haptic effect for
the Braille key mapped to the `` being an initial sound consonant
in order of phonemes constructing a text. After outputting the
haptic effect for the Braille key mapped to the ``, while receiving
a second touch input from the user, the electronic device 101 can
output the haptic effect for the Braille key mapped to the `` being
a vowel. After outputting the haptic effect for the Braille key
mapped to the ``, while receiving a third touch input from the
user, the electronic device 101 can output the haptic effect for
the Braille key mapped to the `` being a final consonant.
[0181] In another example, in case where received information
includes a Korean language text ``, the electronic device 101 can
concurrently output a haptic effect for a Braille key mapped to a
letter unit, for example, each of `` being an initial sound
consonant, `` being a vowel, and `` being a final consonant. For
example, while receiving a touch input from a user, the electronic
device 101 can concurrently output the haptic effect for the
Braille keys mapped to the respective ``, ``, and ``.
[0182] In another example, in case where received information
includes an abbreviated syllable (e.g., ``) or a word (e.g., ``) as
a Korean language text, the electronic device 101 can output a
haptic effect for a Braille key mapped to the abbreviated syllable
`` or the word ``.
[0183] FIG. 11 is a diagram illustrating an example method of
outputting a haptic effect for at least one Braille key among a
plurality of Braille keys according to a further example
embodiment.
[0184] FIG. 11 illustrates an electronic device (e.g., a keypad)
including Braille keys mapped to data (or Braille) corresponding to
numerals.
[0185] In one example embodiment, in case where received
information includes a numeral `101`, the electronic device 1100
can extract `1`, `0`, and `1` by the unit of numeral from the
received information `101`. The electronic device 1100 can output a
haptic effect for a Braille key 1120 mapped to `1`, a Braille key
1110 mapped to `0`, and a Braille key 1120 mapped to `1`, in order
of numerals constructing the received information `101`. However,
it is not limited to this.
[0186] FIG. 12 is a flowchart illustrating an example method of
outputting a haptic effect for at least one Braille key among a
plurality of Braille keys according to another example
embodiment.
[0187] Referring to FIG. 12, in one example embodiment, in
operation 1201, the processor 120 can determine data to output a
haptic effect. For example, the processor 120 can determine the
data to output the haptic effect (hereinafter, referred to as
`determined data`) in order of data constructing a text included in
received information.
[0188] In one example embodiment, in case where a touch input for a
Braille key for which a haptic effect is being outputted is
received from a user, the processor 120 can determine data
corresponding to the next order (or corresponding to the next
arrangement order) of data mapped to the Braille key for which the
touch input is received, as data to output a haptic effect. For
example, in case where received information includes an English
language text `kang`, after the processor 120 outputs a haptic
effect for a Braille key mapped to `a` and receives a touch input
for the Braille key mapped to the `a` from the user, the processor
120 can determine `n` arranged following the `a`, as data to output
a haptic effect.
[0189] In one example embodiment, in operation 1203, the processor
120 can allow to output a haptic effect for a Braille key mapped to
the determined data. For example, the processor 120 can allow to
vibrate a determined Braille key or induce a tactile response of
the determined Braille key, using EMPs included in the determined
Braille key. However, it is not limited to this. For example, the
processor 120 can control the speaker 282 to output Braille mapped
to the determined Braille key in a voice form as well.
[0190] In operation 1205, the processor 120 can determine if a
touch input for the Braille key mapped to the determined data is
received from a user. In one example embodiment, the touch input
for the Braille key can include a touch input (e.g., a drag input),
a multi touch input by at least two or more fingers, a rubbing
touch input (or flicking input), etc. For example, the touch input
for the Braille key can be a touch input rubbing a plurality of
Braille keys from the left to the right using the user's finger for
the electronic device 101 (e.g., keypad). However, it is not
limited to this.
[0191] In one example embodiment, if determining in operation 1205
that the touch input for the determined Braille key is not
received, in operation 1207, the processor 120 can allow to perform
a corresponding function. For example, the processor 120 can allow
to disregard a touch input for another Braille key, not the
determined Braille key. In another example, if receiving a touch
input for another function key, not a Braille key, the processor
120 can allow to execute a function mapped to the another function
key.
[0192] In one example embodiment, in case where the processor 120
determines in operation 1205 that it receives the touch input for
the determined Braille key, in operation 1209, the processor 120
can determine if the determined data is the last data constructing
a text. For example, the processor 120 can determine if it has
outputted all of a text included in received information, or has
outputted a haptic effect for a Braille key mapped to each of the
whole data constructing the text included in the received
information. For example, in case where the text included in the
received information is `kang` and the determined data is `g`, the
processor 120 can determine the data `g` as the last data
constructing the text.
[0193] In one example embodiment, if determining in operation 1209
that the determined data is not the last data constructing the
text, the processor 120 can return to operation 1201 and determine
data following data currently determined (or data corresponding to
the next order), as data to output a haptic effect.
[0194] In one example embodiment, if determining in operation 1209
that the determined data is the last data constructing the text,
the processor 120 can end an information provision operation.
[0195] FIG. 13 is a flowchart illustrating an example method of
outputting a haptic effect for at least one Braille key among a
plurality of Braille keys according to a further example
embodiment.
[0196] FIGS. 14 and 15A, 15B, 15C and 15D are example diagrams for
describing a method of outputting a haptic effect for at least one
Braille key among a plurality of Braille keys according to a yet
another example embodiment.
[0197] Referring to FIG. 13 to FIG. 15A-15D, in operation 1301, the
processor 120 can receive a touch input for a plurality of Braille
keys from a user.
[0198] In one example embodiment, the touch input for the plurality
of Braille keys can include a touch input for the whole plurality
of Braille keys included in the electronic device 101 (e.g.,
keypad).
[0199] In one example embodiment, as illustrated in FIG. 14, the
electronic device 101 can be a keypad consisting of a plurality of
Braille keys 1401 to 1411 each including a dot 1 to a dot 6. In one
example embodiment, in case where the electronic device 101
consists of the plurality of Braille keys 1401 to 1411 each
including the dot 1 to the dot 6 as illustrated in FIG. 14, the
electronic device 101 can output a haptic effect for a Braille key
to represent Braille corresponding to each data included in a
text.
[0200] In one example embodiment, the electronic device 101 of a
keypad form can be implemented to have a size or area that at
contact (or at touch) is covered with the user's hand.
[0201] In one example embodiment, in operation 1303, the processor
120 can allow to sequentially output a haptic effect for a Braille
key that includes dots constructing Braille corresponding to data
constructing a text included in received information.
[0202] For example, while the touch input (or long-touch input or
holding input) for the plurality of Braille keys is received in
operation 1301, the processor 120 can allow to output a haptic
effect for a Braille key including dots constructing Braille
corresponding to data, in order of the data constructing the text
included in the received information. In one example embodiment,
the processor 120 can allow to output the haptic effect for the
Braille key including the dots constructing the Braille
corresponding to the data, at a designated time interval.
[0203] In one example embodiment, in case where received
information is `kang`, as illustrated in FIG. 15A to FIG. 15D, the
processor 120 can sequentially output a haptic effect for Braille
keys 1501 and 1505 including dots constructing Braille
corresponding to `k`, a haptic effect for a Braille key 1501
including a dot constructing Braille corresponding to `a`, a haptic
effect for Braille keys 1501, 1505, 1507, and 1509 including dots
constructing Braille corresponding to `n`, and a haptic effect for
Braille keys 1501, 1503, 1507, and 1509 including dots constructing
Braille corresponding to `k`.
[0204] Though not illustrated in FIG. 13, in case where data
constructing the text `kang` included in the received information
are all outputted, an operation of providing information or an
operation of outputting a haptic effect for a Braille key can be
ended.
[0205] A method for providing information of an electronic device
101 according to various example embodiments can include receiving
information through a communication interface, and outputting a
haptic effect for at least one Braille key among a plurality of
Braille keys, based on the received information.
[0206] In one example embodiment, the plurality of Braille keys can
be implemented using EMPs.
[0207] In one example embodiment, the haptic effect for the at
least one Braille key can include a vibration or tactile response
of the at least one Braille key.
[0208] In one example embodiment, outputting the haptic effect for
the at least one Braille key among the plurality of Braille keys
can include determining data to output the haptic effect based at
least on the received information and, if receiving a touch input
for a Braille key mapped to the determined data, outputting a
haptic effect for the Braille key mapped to the determined
data.
[0209] In one example embodiment, the method can further include,
while receiving the touch input for the Braille key mapped to the
determined data, outputting the haptic effect, and determining data
corresponding to the next order of the determined data, as the data
to output the haptic effect.
[0210] In one example embodiment, outputting the haptic effect for
the at least one Braille key among the plurality of Braille keys
can include determining data to output the haptic effect based at
least on the received information, and outputting a haptic effect
for a Braille key mapped to the determined data.
[0211] In one example embodiment, the method can further include,
if receiving a touch input for the mapped Braille key, determining
data corresponding to the next order of the determined data, as the
data to output the haptic effect.
[0212] In one example embodiment, outputting the haptic effect for
the at least one Braille key among the plurality of Braille keys
can include, if receiving a touch input from a user, sequentially
outputting each of data included in the received information using
the haptic effect.
[0213] In one example embodiment, the method can further include,
if receiving the information through the communication interface,
outputting a notification notifying the information reception.
[0214] In one example embodiment, the electronic device 101 can
include a keypad including a plurality of Braille keys, or a
virtual display displaying the plurality of Braille keys.
[0215] As mentioned above, a method for providing information and
the electronic device 101 supporting the same according to various
example embodiments can make it possible for a user to recognize a
notification of information reception and more accurately identify
information received from the external, by outputting a haptic
effect for at least one Braille key based on the information
received from the external.
[0216] Meanwhile, the aforementioned example embodiments are
possible to be implemented as a program executable in a computer,
and can be implemented in a generic digital computer that operates
the program using a computer-readable recording medium. Also, a
structure of data used in the aforementioned example embodiment can
be recorded in the computer-readable recording medium through
various means. The computer-readable recording medium includes a
storage medium such as a magnetic storage medium (for example, a
Read Only Memory (ROM), a floppy disc, a hard disc, etc.), an
optical reading medium (for example, a Compact Disc-ROM (CD-ROM), a
Digital Versatile Disc (DVD), etc.).
[0217] In one example embodiment, the recording medium can record a
program for executing the operations of receiving information
through a communication interface, and outputting a haptic effect
for at least one Braille key among a plurality of Braille keys
based at least on the received information, in a method for
providing information in the electronic device 101.
[0218] Hitherto, various example embodiments have been described
